title: [The redox potential of the large intestine in swine in relation to swine dysentery].
abstract: The redox potential of (Eh) +111 +/- 25 mV was measured in the large intestine of newly born piglets. In the post-weaning period the Eh values decreased significantly to -173 +/- 27 mV and remained at this level also in the healthy sows (-214 +/- 55 mV). The Eh value recorded in dysenteric pigs was -188 +/- 5 mV, and this was not statistically significant in relation to the healthy weaned piglets. The Eh level measured in the blood agar prepared with cysteine and covered by a thick growth of the strain Treponema hyodysenteriae, which had been incubated in an anaerobic medium for five days, was -218 +/- 18 mV. The Eh of piglets after weaning was not the decisive condition for the development of dysentery. However, it can be assumed that the impossibility of eliciting dysentery in microbe-free and gnotobiotic pigs is associated with a relatively high redox potential of a microbially unpopulated or insufficiently populated intestine.
